[I-345] Wheel Load Running Test of Lightweight Precast Steel-Concrete Composite Slab using Square Steel Pipe
Keywords:Steel-Concrete Composite Slab, Precast, Lightweight Concrete, Square Steel Pipe, Wheel Load Running Test
We are developing precast steel-concrete composite slabs using lightweight concrete and square steel pipes for rapid construction in slab replacement work. Various tests had been conducted to confirm the load bearing capacity, performances of shear connectors and joints of composite slabs. In this study, wheel load running tests were carried out to examine the fatigue resistance of composite slabs. As a result, it became clear that the composite slabs have high fatigue resistance, because there were not destroyed until the end, and no harmful crack was generated in the test specimens.
